  1. Why Groundwater Profilers Use Multiple Optical WavelengthsGroundwater rarely behaves like a uniform body of water. A monitoring well can contain layers with different sediment loads, dissolved minerals, organic…
  2. Understanding Turbidity Monitoring In Environmental Impact AssessmentsEnvironmental impact assessments (EIAs) depend on reliable evidence about how proposed activities may alter water quality. Turbidity is one of the most useful…
  3. Calibrating Turbidity Monitors in Freshwater and Marine WatersA turbidity monitor estimates the cloudiness of water by measuring how particles scatter or absorb light. That measurement is valuable in rivers, lakes,…
  4. Selecting the right suspended-solids sensor for deep-water profilingDeep-water profiling demands more than a sensor that produces a turbidity value at the surface. A suitable instrument must operate reliably under pressure,…
  5. Nephelometric and optical backscatter sensors in water monitoringOptical water-quality sensors provide a practical way to measure turbidity, suspended sediment, and changing particle loads in rivers, reservoirs, coastal…
  6. How Optical Turbidity Sensors Work In Dredging Plume MonitoringDredging removes, relocates, or reshapes sediment beneath the water surface. The work can release fine particles into the surrounding water, creating a plume…
